Mika, There are reasons not to do that:
1. quasselcore.conf is not a user-editable configuration file and arguably isn't a configuration file at all. It stores basically some serialized objects representing the state of the core and changes frequently at runtime. 2. The data directory is a build option and the database along with quasselcore.conf is stored in that directory. To change this behavior you would have to actually patch quasselcore. This is not, of course, a definitive reason not to do it, but does complicate matters. tg
